37 which diagram shows a homologous chromosome pair that has homozygous alleles?

24. The diagram below shows two sets of homologous chromosomes in pea plants. The longer pair carries the gene for pea flower color, where P= purple and p= white. This pea plant is heterozygous, for pea flower color. a. In the figure above, write in the alleles for pea flower color on chromosome pair number one. b. A heterologous chromosome is a chromosome that contains different set of genes for a given trait. Homozygous means that the organism has two copies of the same allele for a gene. Heterozygous means that an organism has two different alleles of a gene.

And how does a gene "know" if it needs to be active or not.

Which diagram shows a homologous chromosome pair that has homozygous alleles?. We have been going in circles with this question. Our DNA has 2 copies of a gene, 1 on each chromosome. If you have an allele of a particular gene, would that mean you'd have 4 copies of the same gene? So confused. Help! Below is a picture of a karyotype, which is a graphic of sorted images showing every chromosome within a cell. Like the one below, most karyotypes show the homologous chromosomes next to each other. Realistically, unless they are lined up during cell division, these homologous chromosomes are randomly distributed throughout the nucleus. with the chromosomes of each homologous pair tangled together. There are thus four chromatids in each pair of chromosomes (N.B. and so only half as many 'sets' visible in diagrams). 2. Portions of each chromatid may break off and reattach to an adjacent chromatid on the homologous chromosome. The places Which diagram shows a homologous chromosome pair that has homozygous alleles? D Karyotypes can be studied to determine an organism's chromosomal makeup and to detect genetic defects.

So I'll give you a little backstory to help understand why it's such a mystery yet somehow I do know about it. When my mom and dad were pregnant with me in '89 my mom was in her later 30s and so for safety they had a prenatal screening done on me as a fetus. The results were abnormal and displayed a trisomy on one of my chromosome pairs. My mom was freaked out and quite frankly was opting for a possible abortion at that point since she wasn't ready to necessarily take care of a special needs c... A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization.Homologs have the same genes in the same loci where they provide points along each chromosome which enable a pair of chromosomes to align correctly with each other before separating during meiosis.

Jun 12, 2018 · The right answer is C (see the images): An organism is heterozygous for a gene when it has two different alleles of that gene on the same locus for each of its homologous chromosomes. An allele is a variable version of the same gene or genetic locus, that is to say, a varied form that can be distinguished by variations in its nucleotide sequence. Alleles can exist in different forms and diploid organisms typically have two alleles for a given trait. These alleles are inherited from parents during sexual reproduction. Upon fertilization, alleles are randomly united as homologous chromosomes pair up. A human cell, for example, contains 23 pairs of chromosomes for a total of 46 chromosomes. Homozygous is a word that refers to a particular gene that has identical alleles on both homologous chromosomes. It is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait. My textbook is giving me two definitions **1st def**: "random orientation of homologous chromosomes at the metaphase plate in meiosis 1." **2nd def**: "alleles for one gene separate into gametes independently of alleles of any other gene (only if genes are on non-homologs or very far apart on same chromosome)." It seems to me that the 1st definition is talking about alleles on homologs themselves and how there's 50% chance that gamete will get paternal and maternal allele of a gene. And I'm g...

The genes are on different pairs of chromosomes. Allele A produces a pink anthocyanin pigment in the spines. Allele B has no effect by itself, but increases the colour produced by allele A to give red spines. Alleles a and b have no effect on spine colour. In the absence of anthocyanin, the spines are green.
